WebPACKING AND GEOMETRY. The reason crystals form is the attraction between the atoms. Because they attract one another it is often favorable to have many neighbors. Thus, the coordination number, or number of adjacent atoms, is important. For a square lattice as shown, the coordination number is 4 (the number of circles touching any individual). WebSep 27, 2024 · These packing lattices contain two types of sites or "holes" that the interstitial atoms fill, and the coordination geometry of these sites is either tetrahedral or octahedral. …

In hcp, the top and bottom three are directly above one another. In ccp, … Web1. As long as ρ ≥ 2 R / ( 2 + 3), all optimal packings follow the same strategy: you can view it as the 2-dimensional problem of packing circles into a tall rectangular strip, with the circles touching the left and right walls alternately. In this case, you can get a formula. For smaller ρ, the problem will be very complicated, like most ...
